The removable air filter is nothing more than plastic or nylon mesh. I don't see how it's going to filter much of anything and I don't see how I can add a a different filter.
The rear of the installed unit doesnot have a protective grill over the cooling fins on the back of the unit. The rear of the case has indentations and mounting holes for a rear protective grill. I called GE customer service and was told the unit didnot ship w/ a protective grill for the the cooling fins. Any suggestiuons how I can get a grill for the back?
